Title: Method and apparatus for modular inversion for information security and recording medium with a program for implementing the method
Inventor: KOBAYASHI TETSUTARO
IPC: G06F7/72
Filed: 1998-11-04
Abstract: The present invention is directed towards a method and system for modular inversion for information security. The modular inversion, including an extended binary GCD, can be determined with a reduced time overhead by the present invention. For determining the modular inversion, digital signals representing values X and N of n-bits and a parameter t are input, then Y is determined where Y is X2-t mod N. Using Y, an extended GCD is used to find S where S is Y-1 2k modN and k and R is determined for S where R is S2-(k+t-2n). A Montgomery inverse of X may be found on a residue class ring Z/NZ using R=X-1 2 2n.

Title: Postage metering system and method for automatic detection of remote postage security devices on a network
Inventor: RILEY DAVID W
IPC: G07B17/00
Filed: 1998-12-14
Abstract: A postage metering system includes a plurality of printer modules connected as part of a network and operating as clients on the network. Postal security devices (PSDs) are coupled the clients. Each PSD is local to the coupled client functioning as a host to the PSD and remote to the other of the plurality of clients. The PSD includes unique identification, postal value storage and a digital signature generator. The clients function as a postage metering network wherein a client requests evidence of postage payment from a remote PSD for concluding postage metering transactions. Each of the clients determines which of the remote PSDs are available for metering transactions on the network by broadcast messages and requests. In one embodiment, a broadcast request for the identity of remote PSDs whose host is logged onto the network is sent over the network by a client when the client logs onto the network. Additional broadcast requests are periodically sent over the network by the client to other clients logged onto the network. Broadcast messages indicating the unique identification of the PSD coupled to a host are sent over the network by the host when the host logs onto the network. Additional broadcast messages are sent periodically over the network by the host. Another broadcast message indicating that a PSD is no longer available is sent over the network by the host when it logs off the network. In alternate embodiments a network server controls broadcast requests and messages.

Patent CA-2264935-A1 (CA)
Inventor: COLCLOUGH MARTIN EAMON
IPC: C07F7/18
Filed: 1997-09-01
Abstract: A process for preparing 1,2- and 1,3-dinitrate esters from polyols containing 1,2- or 1,3-diol fragments involves using an alkyl or aryl boronic acid to form a cyclic boronate ester derivative which is then reacted with dinitrogen pentoxide to directly generate the dinitrate ester. In the cyclic ester form the 1,2- or 1,3-hydroxyl groups are protected and other reactions may then be carried out on other parts of the molecule of which the fragment forms a part, leaving the dinitrate ester to be produced subsequently in the final step. High yields are obtained at both stages.

Title: Hinged member for a rear impact guard
Inventor: SUMRALL DOYLE
IPC: B60R19/56
Filed: 1999-06-17
Abstract: A horizontal impact member for use with a rear impact guard on a semi--trailer truck is disclosed. The horizontal impact member is connected to a standard rear impact guard by a hinge. This design is for use with a liftgate that is mounted to the rear of the semi-trailer truck. As the liftgate travels in a downwardly vertical direction it contacts the horizontal member which rotates along its hinge point. The addition of a roller to the horizontal member reduces the amount of wear upon the horizontal member and the liftgate.

Patent CA-2276366-A1 (CA)
Title: Modular vibration system
Inventor: HOBBS GREGG K
IPC: G01M7/06
Filed: 1997-12-24
Abstract: A modular vibration system which utilizes removable modules to adapt to any of a wide range of applications and performance characteristics. The vibration system comprises a shaker module, a coupling module, and a fixture module. The shaker module includes features for mounting actuators, which provide multiaxial shaking motions, to the shaker module. The fixture module provides for attaching and holding specimens under test. The coupling module, preferably made of a visco-elastic material, couples the fixture module to the shaker module. The fixture module and the coupling module are easily separable from the shaker module. This configuration permits tuning the vibration system, over a wide range of multimodal coupling characteristic between the shaker module and the fixture module, for a specific application by interchanging fixture modules and coupling modules. The coupling characteristics can range from very flexible to very stiff and from underdamped to overdamped. The fixture module can range from a honeycomb structure which is lightweight and flexible to a solid structure which is heavy and stiff. The thickness, shape and composition of the coupling module can be selected to adjust the damping and to provide further tuning of the stiffness. The vibration system can be held together by vacuum applied between the shaker module and fixture module or by constant force tension members such as springs. In some cases the specimen itself can function as the fixture module. Particular modes of vibration can be enhanced or subdued by placement of the actuators.

The pressure activated cohesive pattern forming one edge of the reply envelope can be provided by first and second series of pressure activated cohesive elements that are spaced from each other both in a direction parallel to, and perpendicular to, that side edge. A Z-fold mailer type business form is particularly advantageous.
